◆ solve_magnetic_field()

VectorField3D num::MagneticSolver::solve_magnetic_field	(	const VectorField3D &	J,
		double	tol = `1e-6`,
		int	max_iter = `500`
	)

static

Solve for static magnetic field B given current density J. Solves Laplacian(A) = -mu0*J (Coulomb gauge, Dirichlet A=0) via three CG solves, then returns B = curl(A).
